Pick one of the two methods for stepping down the controllers 5v out to the cell rumble’s 3v
Resistor Method
Buck Converter Bracket
I usually print in PLA+, However regular pla, and rigid resins should work for the bracket
If printing on your own home machine with Cura I recommend doing support blocking around the L-cut on the bottom for the Phob 1’s Teensy pins.
Select the bracket in Cura
Put the support blocking around the L-Cut channel
!! Use one of the two methods to step down the 5v to 3v !!
Cut the motor lead short
splice in the ~23 ohm resistor
Heat shrink over the connections/resistor
Cut the motor leads short, I recycle the remaining wire for the other two connections (you will need to buy the longer wire motor for this though)
Solder the motor positive to the Buck Converter’s v0 (voltage out)
Solder the motor negative, and another negative wire to the buck converter’s GND
Solder a positive wire onto the Buck Converters Vi (Volatage in)
Try to keep the bottom of the buck converter as flush as possible if using the smaller variety
Extra step if using a buck converter
Using a soldering iron at around 200c or as low as possible with a small tip that can slot into the insert. push the three inserts into the Bracket.
The inserts should be pushed in on whatever side it will be screwed in from. So one pushed in from the top, and two on bottom. The proper side has a fillet around the slot that will make the insert easier to place at first.
Personally I will set the insert into the brackets slot, then carefully push the insert in trying to be as perpendicular with the bracket as I can.
the bottom ones can be tricky, I usually just flip the bracket over and put the slotted tab onto the table, then I use the method above.
This Is what the threads should look like after insertion
(semi-optional) I would recommend using some hot glue to help dampen any rattle from the lid and motor, and protect the short motor connection to the resistor.
Screw the lid into place with one of the three m1.6 screws
… just like oem …
I clip the top wings over the Lsliders then pull the bottom over and onto the pcb
Screw it :))
